Testing

About Fm Lab

In the field of plastics, especially in applications with high technical content, it is often necessary to combine agood design and molding with the implementation of specific tests in order to quantify the mechanical- ,thermal- or tribological performance.

In the specificit is possible toperform normed tests, accordingto international standards (ISO orASTM) orspecial testsdeveloped on purpose for the specific product.

In fact, ifon the one handthestandard testsareinternationally recognizedand allow tomake comparisonswith other materials,on the other handthey don’t always provide useful resultsin practice.Furthermore,the performance of aproduct madeof plastic materialdepends, besides the material, even on its geometryandon the transformation process.
For this reason, especially for heavy duty applicationswhich present collisionsand/or wear, it is recommended tocarry outspecific tests.

FMLab offers a special test bench for measuring the stiffness and resistance to bending and/or compression bending, creep, relaxation to tension and fatigue.

The high flexibility of the equipment permit to realize tests on molded parts of large dimensions.Possibility of setting up a stress relaxation test in order to understand and quantify the viscoelastic phenomena typical of polymeric materials. In this way it is then possible to test the real properties of the molded products taking into account the anisotropy due to the presence of reinforcements and the carving effect.

Test bench pin on disk specifically designed to facilitate testing on polymeric materials.

The knowledge of wear phenomena of polymeric materials is still incomplete and very often special tests to quantify it are necessary, therefore ad hoc testing is required to identify the tribological pair equipped with the best performance.

In particular, the test bench supplied to the laboratory is capable of measuring the coefficient of sliding friction and the specific wear rate of anypair tribological metal / polymer and polymer / polymer.

It is possible to mold samples with any kind of thermoplastic material through a mold made especially for testing pairs polymer/polymer or metal/polymer.

Thanks to the great flexibility of the machine test is also possible to study the tribological pairs very special based on the specific application: the polymer / paper, polymer / ceramic, polymer / wood, etc…

Falling Dart impact testerfor measuring the impact resistance of materials and articles.It is possible to perform both tests in accordance with ASTM D5628 and EN ISO 7765 and also special tests on medium/large molded parts.

Very often it is complicated and difficult to predict the impact resistance of articles made with anisotropic materials such as polymers: it is therefore essential to carry out experimental measurements that reproduce the stresses to which the product will be subject during the life of use.

Through special tests, it is possible to creategraphics that define in clear and simple way the range of use of a given product and the variation of fracture energy for different impact conditions.
